IPC: F16C27/06
Abstract: 134,828. Soc. Anon. pour l'Exploitation des ProcÚdÚs Westinghouse- Leblanc. Nov. 7, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Boxes. - The rotors of high-speed machines, such as turbines, rotary compressors, and dynamos are mounted in bearings and stuffing-boxes supported by soft material such as india-rubber, which enables a flexible or rigid shaft to exceed its critical speed and select its own axis of rotation. The shaft a is mounted in light rings c of metal, ebonite, graphite, or lignum-vitµ, which are supported by disks e of india-rubber. Rings k forming joints around the shaft are made of similar material. The soft material may be replaced by springs combined with dash-pots which allow the springs to be easily compressed and to expand slowly. The axis of the machine may be vertical. Specifications 26630/11 and 8527/12, (both in Class 110 (i), Centrifugal and screw fans &c.], are referred to.

Title: Improvements in and relating to liquid fuel burners
IPC: F23D11/10
Filed: 1923-03-15
Abstract: 221,769. Williams, W. W. March 15, 1923. Spray burners; oil supply. - An atomized fuel, oil and air mixture is supplied through a pipe 4 to the firepot 5 of a burner by means of a rotary pressure pump 3 to which the fuel is directly delivered by a measuring device consisting of a pump 6 mounted on the end of the pump 3. The pump 3 comprises a rotor 11 arranged in a cylindrical casing 7 which is fitted with an end-plate 10 and is connected to an oil and air supply pipe 37. The rotor 11 is mounted on the shaft 9 of an electric motor 1 and is formed with three or more slots carrying laminated vanes which when the pump is in operation are thrown out by centrifugal force against the inner surface of the casing 7. The pump 6 comprises a rotor 16 driven by the shaft 9 and arranged in a cylindrical casing 14 formed integrally with the plate 10. An endplate 15 on the casing 14 carries a spring-pressed ball 19 pressing against the rotor 16. A spring-pressed plunger 24 is reciprocated in a socket 23 in the rotor 16 by engagement with a spring-band 21 which is arranged inside the casing 14 and at one point rides over the end of an adjustable screw plug 22. The plunger is guided by a key 26 fitting in a groove 27 in the rotor. Fuel is supplied to a chamber 29 in the casing 14 through a pipe 30. During the revolution of the rotor 16 an aperture 28 in the socket registers with an arcuate slot 32 in a gasket 31 and oil is drawn into the socket. Later in the revolution the aperture 28 registers with a smaller arcuate slot 33 and simultaneously the plunger is pressed inwardly by engagement with the part of the band depressed by the plunger 22. The oil is thereby forced through a pipe 35 to a sight feed cup 36 from which it passes with air from the pipe 38 through the pipe 37 into the pump 3 in which the atomization occurs. The volume, of fuel delivered is regulated by adjusting the screw plug 22. Specification 221,835 is referred to.

As embodied in a wobbleplate motor, a fixed block 21 is formed with cylinders 26 each provided with a pair of pistons 31, 32, the pistons 32 being integral with a pistonrod 33 which co-operates with a wobble-plate 13 secured to a shaft 12. The piston-rod 33 and piston 32 are formed with a shoulder 34 and a groove 35. Ports 28, opening into recesses 27 at the end of the cylinders, are placed in communication-with inlet and outlet ports 14, 15 by means of a valve 16 constructed as described in Specifications 516,721 and 516,764. The ports 14, 15 communicate through lines 77, 82 with a pump 74 and a tank 76. The pump can also communicate through a valve 79 and passages 72, 71 with a groove 70 opening into the cylinders. When the valve 79 is set to cut off the passage 72, both pistons operate the piston-rod. When the valve is set to place the passage in communication with the pump, the piston 31 is held stationary, and the piston-rod is operated by the piston 32 only. The wobble-plate 13 comprises a plate 38 keyed to the shaft 12 and arranged between a shoulder 40 and thrust-bearings 42, 45. An annulus 51, engaging the coned ends of the piston-rods 33, is mounted on a peripheral rollerbearing 50, and ball-bearing 54 arranged to preload the roller-bearing. The inner race 56 of the ball-bearing is secured to the plate by a pin 57 and a split ring 59.

Abstract: 290,301. Westinghouse Electric & Manufacturing Co., (Assignees of Kimmell, W. J.). May 12, 1927, [Convention date]. Vacuum tubes. -A resilient conductor is attached to an electrode so that its elastic force tends to cause it to connect the electrode with the envelope, and the elastic force is opposed by a limb of vaporizable metal, which after evaluation of the envelope, is vaporized so as to form a film on the envelope in contact with the conductor. As shown in Fig. 1, a piece of magnesium 16 is attached to the anode 10, and holds in tension a tungsten wire 12 mounted on a support for the cathode 4. The other electrodes consist of a control grid, not shown, and a screening grid 7, mounted on the foot 2, the lead 6 for the control grid being taken through the top of the envelope. The upper ends of the cathode and grids are spaced by an insulator 9. Two semi-circular discs 11 are mounted on the grid 7 and serve to shield the lead 6 from the anode. After the electrodes have been mounted in position, the magnesium is flashed by induction from an external coil to clean up the gas and form a film 14, Fig. 2 on the envelope. The lead 12 is released and makes contact with the film. Any metal suitable as a getter may be used instead of magnesium. In a modification, the film is not connected with the cathode, but a conducting coating is formed on the outside of the envelope and provided with a lead.

Title: Improvements relating to corrugated plastics pipe
IPC: B29C48/13
Filed: 1967-03-28
Abstract: 1,139,394. Moulding helically corrugated plastics pipe. FURUKAWA DENKI KOGYO K.K. 28 March, 1967 [26 March, 1966; 16 June, 1966], No. 14133/67. Heading B5A. [Also in Division F2] Helically corrugated plastics pipe is made by pressing a hot thermoplastic tube on to the helically corrugated surface of a cylindrical mandrel by applying a pressure differential between the inner and outer surfaces of the tube and rotating the mandrel to advance the tube while cooling the body. The pressure differential is preferably produced by reducing the pressure inside the tube; alternatively the apparatus may use an outside mandrel and the tube be pressed on to the inside of a shaped rotatable cylinder. The apparatus preferably incorporates an extruder to form the tube. As shown, thermoplastic material (p) is extruded by screw 2 and emerges from annular space 7 to form a pipe. Helically corrugated mould section 26 surrounds concentric pipes 22, 23 to which it is rigidly attached by spacers 24. The spacers do not extend round the circumference of the tube and cooling fluid can be pumped into the apparatus through pipe 45; pass along the cavity between cylinders 23 and 27, between the corrugated former 26 and cylinder 27, through holes 23 and back to outlet pipe 46 through the space between cylinders 22 and 23. Gear wheel 40 is rigidly attached to cylinder 27 and serves to rotate the corrugated mould former 26. The plastic pipe is sucked on to the mould former 26 by withdrawing via tube 37 air from the space 72 between the pipe emerging from orifice 7 and the former 26. The pipes may be made of polyethylene, polypropylene, ethylene-propylene copolymer, polystyrene, polycarbonate, polyvinyl chloride, ethylene-vinyl acetate copolymer, polyamide or fluorine containing resins. Relationships between the dimensions of the pipe and the corrugations are also specified. A continuous linear body such as an electrical cable may be inserted in the pipe by passing the body through the apparatus at the same rate as the pipe, so that the pipe is formed round it. If the inside of the apparatus is not at atmospheric pressure, the body must pass through a seal.
